Re^6: passing subroutine references

It's static and lexical to two subroutines.

And yes, localizing a var is a trick. Something that confuses most newcomers to Perl. Localizing a whole typeglob so that you could call the newly created closure as if it was an ordinary subroutine doubly so. If you insist on using local(), localize the $move_disk and define the _hanoi() as an ordinary subroutine accessing the package variable $move_disk.

BTW, what was the last time you actually generated a stack trace?

BTW, what was the last time you actually generated a stack trace? I used `confess` and code analysers on my previous workday. define the _hanoi() as an ordinary subroutine accessing the package variable $move_disk. Yeah, you could make `_hanoi` public, but it doesn't buy you anything to do so.	[reply] [d/l] [select]
